  • Patent number: 11742715
    Abstract: A motor housing (2) has a shaft section to receive a motor shaft (4) and a motor section to receive motor electronics (5) and motor windings (6). The shaft section and the motor section are separated from each other in a sealed manner by a separating pot (7) arranged in the motor housing (2). A metal ball bearing pot (8) with a ball bearing (9) is arranged in the separating pot. The ball bearing pot (8) lies indirectly against a motor housing section that is connected to the outer surroundings, via the separating pot (7). Thus, the motor housing functions as a cooling body. Accordingly, heat generated by the ball bearing (9) during operation is dissipated onto the motor housing and the outer surroundings, via the ball bearing pot (8) and the separating pot (7).

  • Publication number: 20220094237
    Abstract: An electric motor has a motor casing (2) which has a shaft portion for accommodating a motor shaft (4), and a motor portion for accommodating motor electronics (5) and motor windings (6). The shaft portion and the motor portion are separated from each other in a sealed manner by a can (7) in the motor casing (2). The can (7) has a metal ball bearing housing (8) in which a ball bearing (9) for mounting the motor shaft (4) is fastened, and wherein the ball bearing housing (8), indirectly via the can (7), adjoins, with an intermediate gap, a casing cover (3) that forms part of the motor casing (2). The casing cover (3) acts as a heat sink, and heat generated by the ball bearing (9) during operation is dissipated onto the casing cover and into the outer environment via the ball bearing housing (8) and the can (7).

  • Publication number: 20220085675
    Abstract: The disclosure relates to a rotor (1) and an electric motor having the rotor. The rotor is equipped with a permanent magnet (6) extending around an axis of rotation of the rotor, on which a plastic overmolding (3) is provided, which defines a shaft passage (10) for the fastening receptacle of a motor shaft (14) of the electric motor along the axis of rotation, and wherein a press-fit bushing (2), into which the motor shaft can be pressed by a press fit and can be fixed on the rotor, is arranged directly adjoining the shaft passage (10) formed by the plastic overmolding (3).

  • Publication number: 20220085683
    Abstract: The disclosure relates to an electric motor comprising a motor casing (2) that includes a shaft portion for accommodating a motor shaft (4), and a motor portion in which motor electronics (5) and motor windings (6) are arranged, the shaft portion and the motor portion being separated from each other in a sealed manner by a can (7) that is arranged in the motor casing (2). An inner rotor and, axially adjacent thereto, a metal ball bearing pot (8) are arranged in the shaft portion of the can (7), and a ball bearing (9) for mounting the motor shaft (4) is secured in the ball bearing pot (8).
